Abstract
The invention discloses a nitrogen-containing austenitic stainless steel capable of saving nickel and chromium, which comprises the following chemical components in percentage by mass: carbon is less than 0.10; silicon is less than 1.0; 11-15 parts of manganese; phosphorus is less than 0.03; sulfur is less than 0.03; 10-15 parts of chromium; 3.6-5% of nickel; nitrogen is more than 0 and less than or equal to 0.10; the balance being iron. Compared with the prior 18-8 type austenitic stainless steel, the austenitic stainless steel prepared by the invention can save half of nickel, has the advantages of low price, stable performance, simple and convenient production process, easy processing and forming, high yield and the like, is particularly suitable for manufacturing stainless steel plates, strips, wires, bars, pipes and other metal products with various specifications, and is novel stainless steel capable of replacing the 18-8 type stainless steel.
Description
The present invention relates to a kind of austenitic stainless steel, particularly a kind of low nickel chromium triangle and nitrogenous austenitic stainless steel.
At present, austenitic stainless steel such as the 1Cr18Ni9Ti austenitic stainless steel and the 18-8 type chromium-nickel austenitic stainless steel of domestic and international widespread usage, their alloy content is all higher, especially nickel chromium content, be to belong to a kind of high chromium-nickel austenitic stainless steel, the shortcoming that this class stainless steel exists is, the machining deformation drag is big, processing performance is poor, is difficult to machine-shaping, and its production technique is also complicated, and because the content height of nickel chromium triangle, cost is increased, cause this class stainless steel to cost an arm and a leg, use this class stainless steel uneconomical.
The object of the present invention is to provide a kind of cheap, production technique is easy, good processability and the strong nitrogenous austenitic stainless steel of anti-oxidant resistance to corrosion.
The objective of the invention is to be achieved through the following technical solutions, nickel-chromium-saved nitrogen-contained austenite stainless steel, its Chemical Composition (quality %) is: carbon＜0.10; Silicon＜1.0; Manganese 11～15; Phosphorus＜0.03; Sulphur＜0.03; Chromium 10～15; Nickel 3.6～5; 0＜nitrogen≤0.10; All the other are iron, make austenitic stainless steel in the formula range of technique scheme, and the scheme that can preferentially select is: carbon＜0.06; Silicon＜0.8; Manganese 11.5～12.5; Phosphorus＜0.03; Sulphur＜0.03; Chromium 12.5～13.5; Nickel 3.6～4.5; 0＜nitrogen≤0.10; All the other are iron.Stainless Steel Alloy of the present invention, be to utilize carbon drop, low nickel, low chromium, the nitrogenous prescription of manganese addition obtains a kind of excellent property, the austenitic stainless steel alloy of good stability, carbon wherein, nitrogen, nickel, manganese all is austenite former, when design, its starting point is to reduce cost, guarantee that again its performance is not less than existing performance of austenitic stainless steel, so when taking to reduce price very expensive nickel chromium content and corresponding minimizing chromium content scheme, also take to reduce carbon content, the measure of corresponding increase manganese content and adding proper N guarantees the performance after the reduction nickel chromium content constant, make its same favorable tissue stability that obtains, the cold working viscous deformation does not have precipitated phase.Wherein, especially added an amount of nitrogen, stabilization of austenite, mechanical property, corrosion resistance nature all have been improved, and have high toughness.
The present invention compares with above-mentioned austenitic stainless steel described in the prior art, have following significant effect: (1) obviously descends cost owing to reduced nickel chromium content in prescription, compares with 18-8 type austenitic stainless steel, the joint nickel half, low price about 30%; (2) austenitic stainless steel of the present invention, on mechanical property, be better than the 18-8 type austenitic stainless steel that generally uses, this stainless steel is because Ni and Cr contained is lower in addition, the work hardening phenomenon is lower than 18-8 type austenitic stainless steel significantly, also because carbon is also low, so processing characteristics, deep drawability also all are better than existing 18-8 type austenitic stainless steel; (3) because this stainless steel contains total alloy amount low (nickel chromium triangle), and carbon containing is also lower, makes production technique easier, and plasticity is good, is easy to machine-shaping, yield rate is also higher.The austenitic stainless steel alloy that the present invention makes is a kind ofly can substitute the stainless novel stainless steel of expensive 18-8 type in the wide industrial field, is specially adapted to make stainless steel materials, band, a material, bar, tubing and other metal products of various descriptions.
Nickel-chromium-saved nitrogen-contained austenite stainless steel of the present invention can further specify by the embodiment of following two concrete prescriptions.
Embodiment 1, and nickel-chromium-saved nitrogen-contained austenite stainless steel alloy ingredient (quality %) is: carbon 0.098, and silicon 0.95 manganese 13.5, phosphorus 0.028, sulphur 0.026, chromium 14.5, nickel 4.88, nitrogen 0.08, all the other are iron.The stainless steel of smelting with this alloy ingredient rolling φ 8mm dish unit 1020 ℃ of solution treatment in footpath, by pickling, upward lubricated carrier carries out wire drawing, made silk material φ 3.0mm and φ 2.0mm can be used for high-grade motorcycle, bicycle spoke.By comprehensive Performance Detection, the steel wire that is used to make motorcycle and bicycle spoke satisfies the technological standard of motorcycle and bicycle spoke fully, also all meets related standard requirements through tracking test.
Embodiment 2, and nickel-chromium-saved nitrogen-contained austenite stainless steel alloy ingredient (quality) is: carbon 0.056; Silicon 0.62; Manganese 11.72; Phosphorus 0.024; Sulphur 0.021; Chromium 12.55; Nickel 3.86; Nitrogen 0.012; All the other are iron.With the stainless steel that this alloy ingredient is smelted,, handle through 1020 ℃ of lights again through hot rolling 4 * 200mm stainless steel plate, cold rolling at last, the Stainless Steel Band 0.5 * 200mm after cold rolling is used for deep-draw instrument components and parts, stretched and the distortion of material all meets related standard requirements at last after testing.
Above-mentioned two examples all are with low-carbon waste steel, the low-carbon (LC) nitrided ferro-chromium, low carbon ferromanganese, metallic nickel and an amount of mixed additive of adding etc. are raw material, smelt through arc furnace or non-vacuum induction furnace, in melting, will note grasping the oxygen blast carbon drop, fully deoxidation and slag making in the melting, in strict accordance with the smelting technology accurate operation, the later stage slagging-off.Sampling analysis after the melting, qualified timely steel tapping casting becomes ingot casting.Check Ingot Surface Quality after the ingot casting demoulding, bad as Ingot Surface Quality, need carry out the emery wheel reconditioning, can carry out hot rolling cogging, be rolled into stockings such as slab, made-up belt, pipe, dish unit at last for next procedure cold working.
